A    LIST    OF    A    COLLECTION    OF    MEXICAN    MAMMALS   WITH 
DESCRIPTIONS  OF  SOME  APPARENTLY  NEW  FORMS. 


BY    D.  G.  ELLIOT,  F.  R.S.  E.,  ETC. 


This  small  collection  of  mammals  was  obtained  by  Mr.  F.  E. 
Lutz,  who  accompanied  Dr.  S.  E.  Meek  in  his  visit  to  Mexico  in 
1901.  The  new  forms  have  been  compared  with  the  types  of  Dr. 
Merriam's  species  and  the  examples  in  the  large  collection  from 
Mexico  belonging  to  the  Biological  Survey  in  Washington,  and  my 
thanks  are  due  to  Dr.  Merriam  and  Mr.  W.  H.  Osgood  for  their  kind 
assistance  during  my  visit  to  the  National  Museum,  and  for  facilities 
given  for  examining  their  specimens.

GENUS    PEROMYSCUS. 

Peromyscus.     Glog.  Handb.  &  Hilfsb.  Natur. ,  1842,  p.  95. 

Peromyscus  1.  sonoriensis.  (Le  Conte)  Proc.  Acad.  Nat. 
Scien.  Phila.,  1853,  p.  413. 

Twenty  specimens:  19  from  Ocotlan,  State  of  Jalisco,  and  i 
from  Patzcuaro,  State  of  Michoacan. 

These  specimens  of  this  widely  dispersed  species  are  practi- 
cally identical  with  those  from  Woodford,  Alpine  County,  Cali- 
fornia, obtained  by  W.  W.  Price  in  1895. 

Peromyscus  *sagax.     Sp.  nov. 

Five  specimens  from  Patzcuaro,  State  of  Michoacan:  two 
adults,  three  young. 

Type  locality.      La  Palma,  State  of  Michoacan. 

Gen.  cliar.  Similar  in  color  to  P.  difficilis,  but  cranial  char- 
acters different.  Ears  large.  Skull  :  brain  case  nearly  square, 
broad;  interorbital  constriction  considerable.  As  compared  with 
skull  of  P.  difficilis,  that  of  the  present  species  is  shorter  and  nar- 
rower with  shorter  nasals  but  of  about  equal  width;  bullae  smaller 
and  closer  together  and  molars  much  smaller. 

Color.  Top  of  head  and  dorsal  region  mixed  grayish  black 
and  buff,  the  former  predominating;  sides  grayish  brown  and  buff 
with  an  indistinct  buff  lateral  line;  orbital  ring  and  spot  behind 
nose  black,  with  a  buff  spot  between  it  and  the  eye;  sides  of  head 
and  shoulders  buffy  gray;  sides  like  thighs;  hands  and  feet  white. 
Tail  dusky  above,  white  beneath;  ears  large,  brown  at  base, 
blackish  at  tip  with  narrow  white  edges. 

Measurements.  Total  length,  192;  tail  vertebrae,  107:  hind 
foot,  22.  Skull:  total  length,  26;  Hensel,  20;  zygomatic  width, 
33:  mastoid  width,  12;  length  of  nasals,  10;  greatest  width  of 
rostrum,  4;  palatal  length,  4:  interorbital  constriction,  4;  length 
of  incise  foramina,  4;  length  of  upper  molar  series,  4;  of  lower 
molar  series,  4. 

While  resembling  the  type  of  P.  difficilis  in  gene/al  color 
without  any  rufous  tinge,  the  present  form  has  smaller  ears  and 
a  shorter  tail  with  marked  cranial  differences  as  given  above. 

Peromyscus  -ipavidus.     Sp.  nov. 

Three  specimens  from  Patzcuaro,  State  of  Michoacan. 

Type  locality.      Patzcuaro,  State  of  Michoacan,  Mexico. 

Gen.  cliar.  Tail  long;  ears  large;  colors  pale.  Skull  with  a 
very  broad  brain  case;  mastoid  width  the  greatest;  rostrum  long

and  rather  slender,  its  greatest  width  being  less  than  the  least 
interorbital  width;  the  palatine  foramina  broad,  their  posterior 
ends  just  reaching  the  anterior  line  of  first  premolar.  Skulls  of 
all  the  specimens  badly  broken.  Somewhat  similar  to  P.  gratus 
in  color,  but  larger  in  all  its  measurements. 

Color.  Upper  parts  mixed  buff  and  brownish  black,  palest 
on  hind  neck;  orbital  ring  black;  lateral  line  from  lip  to  rump 
ochraceous  buff;  sides  above  it  buff:  under  parts  white  tinged  with 
buff  on  chest;  arms  buff;  legs  and  ankles  dusky;  hands  and  feet 
white;  tail  above  blackish  or  brownish  black,  beneath  white;  ears 
brown. 

Measurements.  Total  length,  238;  tail  vertebrae,  130:  hind 
foot,  23;  ears,  20. 

This  large  mouse  in  its  rather  light  color,  large  ears  and 
long  tail  does  not  resemble  very  closely  any  of  the  named  forms 
that  would  naturally  be  arranged  with  it.  It  is  a  rather  con- 
spicuous species  and  would  readily  attract  attention  in  a  collec- 
tion of  these  animals.  Unfortunately  the  skuil  is  badly  broken 
and  exact  measurements  cannot  be  given.  « 

Peromyscus  *labecula.     Sp.  nov. 

Six  specimens  from  Ocotlan,  State  of  Jalisco. 

Type  locality.     Ocotlan,  State  of  Jalisco,  Mexico. 

Gen.  char.  Similar  to  P.  thurberi  in  general  color,  but 
cranial  characters  very  different.  Tail  short.  Skull  as  compared 
with  that  of  P.  thurberi  has  brain  case  more  square  shaped;  outer 
edge  of  frontals  more  curved;  interorbital  constriction  greater; 
nasals  shorter  and  broader  anteriorly;  palatine  foramina  shorter 
and  narrower;  pterygoids  shorter:  maxillary  branch  of  zygoma 
broader  and  heavier.  Pelage  soft,  thick,  white  spot  at  base  of  ear. 

Color.  Above  dark  grayish  fulvous,  top  of  nose  grayish  buff; 
conspicuous  white  spot  at  posterior  base  of  ears;  shoulders  mixed 
buff  and  black;  lateral  line  from  upper  lip  to  thigh  tawny 
ochraceous:  lips  and  under  parts  white;  thighs  like  sides:  arms, 
hands  and  feet  white;  tail  hairy,  above  blackish  brown,  sides  and 
beneath  white;  ears  small,  black  edged  with  white. 

Measurements.  Total  length,  144;  tail,  57;  hind  foot,  18. 
(Skin.)  Skull:  greatest  length,  25;  Hensel,  20;  zygomatic  width, 
13;  mastoid  width,  n;  length  of  nasals,  10;  greatest  width  of 
rostrum,  4;  palatal  length,  4;  length  of  upper  tooth  row,  4. 

This  little  mouse  resembles  P.  thurberi  in  its  general  hue, 
although  somewhat  darker  above,  but  is  distinguishable  from

North  American  mice  by  the  rather  conspicuous  white  spot 
behind  the  ears.  Only  six  specimens  were  procured,  all  of 
which  were  unfortunately  injured  by  cats.

GENUS    SIGMODON. 

Sigmodon.     Say  &  Ord.,  Journ.  Acad.  Nat.  Scien.  Phil.,  1825,  p.  352. 
Sigmodon  hispidus  ""inexoratus.     Subsp.  nov. 

Sixteen  specimens  from  Ocotlan,  State  of  Jalisco,  Mexico. 

Type  locality.      Ocotlan,  State  of  Jalisco,  Mexico. 

Gen.  char.  Size  large.  Similar  to  .S.  hispidus,  back  grayer 
above  and  paler  on  sides.  Infraorbital  foramen  oblong  and  nar- 
row. Skull  broad  in  front. 

Color.  Above  creamy  buff  heavily  lined  with  black:  sides 
cream  buff;  arms,  hands  and  thighs  cream  buff:  hind  feet  gray; 
under  parts  grayish  white;  tail  sparsely  haired,  blackish  above, 
whitish  beneath;  ears  dark  brown. 

Measurements.  Total  length,  310:  tail  vertebra,  146;  hind 
foot,  36;  Skull:  total  length,  37;  Hensel,  31;  zygomatic  width, 
20;  mastoid  width,  15:  median  palatal  length,  8:  length  of  incisive 
foramen,  7;  upper  tooth  row.  7:  lower  tooth  row,  7. 

These  specimens  do  not  seem  to  agree  with  any  described 
forms.  In  size  they  are  about  equal  to  the  large  major  and 
tona/cnsis,  but  are  otherwise  quite  different,  and  while  approach- 
ing mascotcnsis  in  cranial  characters,  they  are  much  larger  and  of 
a  different  color.

One  specimen. 

This  species  of  cotton  rat  has  a  coloring  not  unlike  many 
forms  of  the  Rice  rat  (Oryzomys),  and  is  a  rather  small  species. 

GENUS    ORYZOMYS.

Oryzomys  *molestus.     Sp.  nov. 

One  specimen  from  Ocotlan,  State  of  Jalisco. 

Type  locality.      Ocotlan,  State  of  Jalisco,  Mexico. 

Gen.  char.  Size  large:  ears  small:  tail  very  long;  color 
"beneath  uniform.  Skull  about  half  as  broad  as  long;  supraor- 
bital  beads  diverging  posteriorly  from  least  interorbital  width  in 
almost  straight  lines;  unlike  those  of  O.fulgens;  palatal  arch  with 
an  azygos  point;  palatine  foramina  very  long  and  broad. 

Color.  Above  dark  fulvous;  flanks  pale  buff;  forehead  darker 
than  back;  under  parts  grayish  white:  tail  nearly  naked,  pale 
brown  above,  lighter  beneath:  ears  pale  brown. 

Measurements.  Total  length,  325;  tail  beneath,  170;  hind 
foot,  38.  Skull:  greatest  length,  35;  Hensel,  28;  zygomatic 
width,  18;  mastoid  width,  14;  length  of  nasals,  14;  width  of 
rostrum,  6;  interorbital  constriction,  6;  palatal  length,  7;  length 
of  upper  tooth  row,  6. 

This  is  one  of  the  largest  species  of  the  group  and  is  nearest 
to  O.  fulgens,  but  differs  from  that  form  in  its  darker  color  on  the 
upper  parts,  and  in  being  grayish  white  below  instead  of  washed 
with  fawn.  Unfortunately  but  a  single  example  was  procured, 
and  as  the  type  locality  of  O.  fulgens  is  unknown  the  two  animals 
may  be  widely  separated  in  their  habitats.  I  have  compared  the 
present  specimen  with  the  large  series  in  the  collection  of  the 
Biological  Survey  in  the  National  Museum,  Washington,  and  it 
did  not  agree  with  any  of  the  examples.

Rhithrodontomys  tinexspectatus.     Sp.  nov. 

Type  locality.      Patzcuaro,  State  of  Michoacan,  Mexico. 

Gen.  char.  Similar  to  fi.  levipes,  but  whitish  on  under  parts 
instead  of  pale  fulvous,  and  tip  of  tail  white.  Ears  large;  tail 
long. 

Color.  Upper  parts  mixed  black  and  tawny  ochraceous; 
sides  ochraceous  buff;  chin,  upper  part  of  throat,  hands  and  feet 
white;  under  parts  grayish  white,  slightly  tinged  with  buff;  limbs 
like  sides.  Tail  above  blackish  brown,  tip  white,  beneath  whit- 
ish. Ears  naked,  dark  brown  with  a  slight  edging  of  brown  and 
a  tuft  of  ochraceous  hairs  at  base.

146  FIELD  COLUMBIAN  MUSEUM — ZOOLOGY,  VOL.  III. 

Measurements.  Total  length,  180:  tail  vertebrae,  113;  hind 
foot,  21.  Skull  much  broken;  lengjth  from  alveolus  of  incisors  to 
posterior  end  of  palate,  9;  length  of  palate,  5;  length  of  nasals,  9; 
least  interorbital  width,  3;  length  of  upper  tooth  row,  4. 

I  compared  this  specimen  with  Dr.  Merriam's  numerous 
types  and  the  extensive  series  in  the  Biological  Survey  collection, 
but  it  differed  from  them  all  save  one.  This  was  an  example 
from  Patzcuaro,  the  type  locality,  which  had  probably  been  over- 
looked and  had  not  been  named.

One  specimen  from  Patzcuaro. 

This  specimen  represents  the  typical  style  from  Hacienda 
Angostura,  State  of  San  Luis  Potosi.  It  is  a  dark  animal  with 
the  central  dorsal  region  slightly  darker  than  the  rest,  but  with- 
out any  distinct  saddle. 

Heteromys  albo-limbatus.    Gray,  Proc.  Zool.  Soc. ,  1868,  p.  205. 

Two  examples;  one  from  Patzcuaro,  State  of  Michoacan,  and 
one  from  Puenta  de  Ixtla,  State  of  Morelos. 

This  species,  while  resembling /f.  alleni  \\\  its  general  appear- 
ance, is  rather  lighter  in  color  and  with  a  very  distinct  saddle. 

Heteromys  *exiguus.     Sp.  nov. 

One  specimen. 

Type  locality.      Puenta  de  Ixtla,  State  of  Morelos. 

Gen.  char.      Size  small;  no  lateral  line:  well  marked  saddle. 

Color.  Above  mixed  buff,  brownish  black  and  dark  gray 
forming  a  well  marked  dark  saddle  on  middle  of  back;  sides  of 
head,  neck  and  body,  with  rump  and  thighs,  light  gray:  lips, 
under  parts  and  hands  white;  arms,  legs  and  feet  yellowish  white; 
no  lateral  line;  tail  above  blackish  brown,  beneath  white.

Measurements.  Total  length,  185;  tail  vertebrae,  106;  hind 
foot,  24.  The  skull  is  badly  broken  and  no  measurements  are 
possible. 

Dr.  Merriam  has  raised  the  members  of  this  group  of  the 
Heteromyidae  to  generic  rank  under  the  title  of  Liomys  (1.  c. ).  It 
does  not  appear  to  me  that  the  characters  he  gives  are  sufficiently 
distinctive  and  important  for  this,  as  adults  of  Liomys  and 
Heteromys  in  a  number  of  instances  cannot  be  distinguished 
apart  by  their  teeth  and  therefore  Liomys  is  here  employed  as  a 
subgenus.  I  sent  the  specimen  of  H.  exiguus  to  Dr.  Merriam  to 
be  compared  with  his  large  series,  and  he  writes  me  that  "it  is 
different  from  any  species  known  to  me,  although  it  is  closely 
related  to  L.  torridus  minor.  Our  collection  does  not  contain 
anything  like  it."

Lepus  floridanus  *persultator.     Subsp.  nov. 

Type  locality.      Puebla,  State  of  Puebla. 

Gen.  char.  In  color  closely  resembling  L.  f.  subcinctus,  but 
smaller  in  all  its  measurements.  Skull  is  distinguished  for  the 
straightness  of  its  anterior  superior  outline,  the  nasals  being  flat 
and  on  a  line  with  the  frontals;  posterior  portion  of  skull  from 
behind  orbits  curving  sharply  downward.  Nasals  broad, 
abruptly  compressed  near  anterior  termination;  palatal  arch  with 
azygos  process  in  center.  Ears  short. 

Color.  Top  of  head  cinnamon  rufous  and  black;  rest  of 
upper  parts  except  rump  mixed  black  and  ochraceous  buff;  sides 
gray;  rump  mixed  gray  and  black;  nape  and  outer  surface  of 
limbs  yellowish  rufous;  stripe  of  ochraceous  buff  on  body  in  front
